If it isnt a joke, don't do it, you couldn't go to jail. If you really do it, try not to let anyone see you or any surveillance cameras see you. When you have the car (if you know how to drive) take it to a distant and hidden place, for example, a mountain and some abandoned place. When you are there, put on some gloves and protection to avoid leaving fingerprints (also make sure that no one sees you or that the prints of your sneakers do not leave a trace). Spray the car with gasoline and then walk away so that when it comes time to burn it you don't get hurt.
